Schwartzian transforms

[Dan Sugalski]

While all the discussion around Schwartzian transforms is interesting, the 
single ultimate question is:

   "Can perl automatically optimize away function and tie calls inside
    a sort function, and under what circumstances?"

It doesn't really matter if the functions inside the sort function are 
idempotent--what matters is whether it's OK for us to go and memoize the 
things (or whatever else we might choose to do)
